Adding physics from GLTF directly

[JaimeTorrealba]

Description

There is an update in the GLTF structure, now they can accept physics, babylonJs already have implemented it, but there's no example with Three.js. So this could be hard to do.

As we need to investigate if this is possible directly here in this pkg, if we need to make changes in the GLTF parser provided by Three.js (or if we can extend it) and the match them with the components provided by Rapier itself.

Please read the link below for more information.

Suggested solution

Much of the result will define the output. But reading about it, a new component could be a good solution.
import { PhysicalGLTF } from ...` (of course the name has to be defined).

Other option could be adding extension to the existing useGLTF composable provided by cientos

I would prefer not to modify cientos directly for this one. WDYT?

Alternative

Any other alternative is welcome
